Analysis for UAV Heuristic Tracking Path Planning Based on Target Matching

Target tracking is a hot research direction in the UAV path planning, and there are many related researches, especially for the design of algorithms. In this paper, the heuristic tracking path planning is studied from the aspects of target matching, algorithm design and parameters analysis, realizing the autonomous processing ability of UAV from target selection to path planning, and the influence of each parameter on the path planning result was emphatically analyzed. In the process of target matching, the Hungarian algorithm was used to solve the problem. During the path planning process, the target tracking A* algorithm was designed. The parameters analysis mainly includes the step size, turning angle, the proportion of the heuristic function and the number of threats in the flight node expansion process. The simulation result of tracking path planning is given in the article, which shows the feasibility of this method.
